HDPE is recommended over other plastics due to it being denser and thus better at blocking very narrow direct sound beams, and because it can block lower frequencies. Acrylic is recommended for windows and other areas that require light to pass through. {{ti-resources: | Most plastics absorb sounds releasing is energy as heat.

| + | Water can both block EMF and sound making it the most effective inexpensive solution. With EMF it works because it has many free ions and can conduct electricity and thus is metals used by Faraday. Water can pass sound, but waves entering the water from the air are largely reflected back and refracted (up to 99%) changing direction. When enclosed within solid container this is less effective and only some sound is blocked by refraction. Water is difficult to use when building protection area, but it can be tried using flat water tanks in a frame. | ||

| - | ==== Sound Proofing Materials Theory | ||
| - | |||
| - | <wrap todo> This draft needs to be re-written to explain physics theory and define key words and concepts</ | ||
| - | |||
| - | Sound beams and waves can be interrupted and protected against by sound absorbing and blocking (sound proofing) and sound-reflection materials. When sound waves in the air are vibrations of air particles, while in the material vibrations within material structure. Many materials are almost as good for sound wave transmission as air. However rigid materials bend as wave travels absorbing its energy which is released as heat. Air packets that trap the sounds greatly help in this process. Such materials are good for sound proofing and sound protection, most popular of these are rigid synthetics and plastics - Fiberglass, Mineral Wool, and Polyurethane Foam. | ||
| - | |||
| - | When the sound wave hits any boundary, be it air boundary when it hits some material, or boundary between two different types of materials, then part of the wave is reflected back. Materials that reflect large part of the wave are also good for sound protection and blocking. This include metals, glass, concrete, and water. | ||
| - | |||
| - | Materials further differ by how well they protect against different frequencies. While rigid synthetics are in general very good at absorbing frequencies above 1kHz (majority of audible range and ultrasound) they start to fail at lower range audible range and infrasound because of the long wave length corresponding to shorter frequencies. Sound reflection materials generally work about the same and necessary part of sound-proofing design where low frequency sounds and infrasound are frequent. This includes protection against gangstalker' | ||
| - | |||
| - | Another important materials parameter is its density. Denser materials are better at sound absorption but are more expensive. Rigid synthetics used in sound-proofing vary from 2# (lb) per sq ft to 8# (lb) per sq ft with 3# and 6# being most common. Higher density rigid synthetics can partially compensate for their lower performance with low frequencies, | ||
| - | |||
| - | Hard materials that have good sound absorption qualities are plastics - HDPE (High Density Polyethylene), | ||
| - | |||
| - | Why water is a strong blocker of sound waves: | ||
| - | * Acoustic Impedance: | ||
| - | * Sound Speed and Density: The speed of sound in water is significantly higher than in air. Water is also much denser than air. | ||
| - | * Critical Angle: Sounds waves that hit the boundary between air and water at an angle higher than the critical angle are almost entirely reflected. Based on the difference between air and water, the critical angle is fairly low. | ||
